Since 1d0fa89 (checkout: add --ignore-other-wortrees, 2015-01-03) we have a safety valve in checkout/switch to prevent the same branch from being checked out simultaneously in multiple worktrees.
If a branch is bisected in a worktree while also being checked out in another worktree; when the bisection is finished, checking out the branch back in the current worktree may fail.
Let's teach bisect to use the "--ignore-other-worktrees" flag.
